Apple Cider Vinegar (ACV) is a type of vinegar made from fermented apple juice. The process involves crushing apples, extracting their juice, and then fermenting it with yeast and bacteria. This fermentation converts the sugars in the juice into alcohol, which is further transformed into acetic acid, giving ACV its distinct sour taste and strong aroma. ACV is often used in cooking, salad dressings, and as a natural preservative. Some people also use it for its potential health benefits, which may include aiding digestion and supporting weight loss. However, scientific evidence on these benefits is still limited.
